Question:

A long straight wire AB carries current 10 A. A proton (P) travels with a speed $2×10^6 m/s$, parallel to the wire, at a distance 2 m from it in a direction opposite to the current as shown in figure. The force experienced by the proton is: $(μ_0=4π×10^{-7}NA^{-2})$

Options:

$4×10^{-2}N$

$6×10^{-10}N$

$3.2×10^{-19}N$

$6.9×10^{-13}N$

Correct Answer:

$3.2×10^{-19}N$

Explanation:

The correct answer is Option (3) → $3.2×10^{-19}N$
